I'm trying to set a timeout for my HTTP request while using an async call (getasyncresponse). However I noticed Timeout doesn't work for async calls.

As this call is not a blocking call you can decide to ignore it and don't handle the response.

But it's used to download screenshots, files and information. I must be able to do something when there's no connection (put a filler screenshot image, stop the download and show an error message).

I really need to have a timeout. Maybe using timers? :sign0085: Is there any way to stop a response call? I would stop the call after 5 seconds using a timer's tick event.

Currently it is not possible to cancel the request. However you can use a timer to test if the response event was not fired after 30 or 60 seconds (5 seconds is not enough) show an error message and later ignore the response event if it will fire.

Somthing like:

B4X:

Sub Globals
   ignoreResponse = false
End Sub

Sub App_Start
     Form1.Show
     request.New1(URL)
     response.New1
     request.GetAsyncResponse
      ignoreResponse = false
      Timer1.Enabled = true 'interval = 30000

End Sub

Sub Timer1_Tick
 Timer1.Enabled = false
 ignoreRequest = true
 msgbox("Error connecting to site.")
End Sub


Sub request_Response
 if ignoreRequest then return
 ...
End Sub
